DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mainly cleaning a sensor of a photoelectric smoke detector and checking the same.

[0002]

2. Description of the Related Art In general, a sensing unit of a photoelectric smoke detector includes:
The optical sensor is configured to be covered by a cover. Dust easily accumulates in the cover, and the accumulated dust may cause malfunction of the smoke detector. Therefore, it is necessary to remove the dust in the cover as needed. Conventionally, when removing dust, a cover is removed and cleaning is performed.

[0003] The operation of the smoke detector is checked by using an inspection tool provided with a pot-shaped member at the tip of a support rod, surrounding the sensing portion with the pot-shaped member, and sending incense smoke into the pot-shaped member. This is done by having the light sensor detect smoke.

[0004]

However, since the smoke detector is mounted on the ceiling, it is necessary to climb a stepladder or the like to remove the cover, and the operation check is performed separately from the dust removal operation. In large buildings with many smoke detectors,
It took a lot of time to maintain and manage the smoke detector.

Accordingly, an object of the present invention is to provide an apparatus capable of easily performing cleaning and inspection work of a smoke detector.

[0006]

In order to solve the above-mentioned problems, the present invention provides a pot-shaped member at the tip of a support rod, which can surround a sensing portion of a smoke detector, and the pot-shaped member has an air inlet and a note. Forming a water inlet and an air inlet, a suction device at the air inlet through an air inlet pipe, a pump at the water inlet through a water inlet pipe,
A configuration was adopted in which a dryer was connected to the air inlet through an air pipe.

[0007]

In the smoke detector cleaning device configured as described above,
When supporting the support rod and surrounding the sensing part of the smoke detector with a pot-shaped member and operating the suction device, the dust in the sensing part that has peeled off from the inner wall of the sensing part via the intake port, intake pipe It is sucked into the suction machine.

Next, the pump is operated, and a water injection pipe is
When the cleaning liquid is jetted into the sensing unit through the water inlet, dust attached to the inner wall of the sensing unit is washed away, and the washed-out dust is sucked into the suction device together with the cleaning liquid through the suction port and the suction pipe. At this time, since the smoke detector is activated by the cleaning liquid diffused in the sensing unit, the operation check of the smoke detector can be performed simultaneously with the cleaning.

Then, when the dryer is operated, hot air is sent into the sensing unit through the air supply pipe and the air inlet, and the hot air dries the inner wall of the sensing unit.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 and 2, a pot-shaped member 2 that can surround the sensing unit S of the smoke sensor is provided at the tip of the support bar 1. A packing 3 is attached to the upper opening edge of the pot-shaped member 2, and a receiving tray 4 that can contact the bottom wall of the cover of the sensing unit S is provided inside the pot-shaped member 2. An inlet 5, a water inlet 6, and an air inlet 7 are formed on the peripheral wall of the pot-shaped member 2.

The support rod 1 is provided with an air passage therein, and one end of a flexible hose 8 is connected to a base end thereof.
The support rod 1 and the flexible hose 8 constitute an intake pipe 9. Through the intake pipe 9, the intake port 5
Is connected to a pump 12 via a water supply pipe 11 and a dryer 14 via a water supply pipe 13 to the air supply port 7, respectively. The water injection pipe 11 and the air injection pipe 13 are made of a flexible vinyl tube, and are bundled with the support rod 1 respectively. The pump 12 is also mounted on the support bar 1. In this embodiment, the suction mechanism and the dryer 14 use the suction mechanism and the exhaust mechanism of the vacuum cleaner 15 capable of absorbing water, respectively.

In the above-described apparatus for cleaning a smoke detector, the support rod 1 is supported, the receiving tray 4 is brought into contact with the bottom wall of the cover of the sensing section S, and the pot-shaped member 2 surrounds the sensing section S so as to be electrically operated. When the vacuum cleaner 15 is operated, as shown in FIG. 3, of the dust in the sensing unit S, the dust that has separated from the inner wall of the sensing unit S is sucked into the vacuum cleaner 15 via the suction port 5 and the suction pipe 9. It is.

Next, when the pump 12 is operated and the cleaning liquid is jetted into the sensing portion S through the water injection pipe 11 and the water inlet 6, dust adhering to the inner wall of the sensing portion S is washed away as shown in FIG. . Water may be used as the cleaning liquid, but the use of a detergent solution improves the cleaning power. The washed-out dust is sucked into the vacuum cleaner 15 through the suction port 5 and the suction pipe 9 together with the cleaning liquid. At this time, since the smoke detector is operated by the cleaning liquid diffused into the sensing unit S, the operation check of the smoke detector can be performed simultaneously with the cleaning.

Further, as shown in FIG.
Since hot air is sent into the sensing unit S from the exhaust mechanism through the inlet pipe 13 and the inlet 7, the inner wall of the sensing unit S can be dried immediately after the pump 12 stops.

If a switch 16 is provided on the vacuum cleaner 15 on the outer periphery of the base end of the support bar 1, the operability is improved.

In addition, the water supply pipe 11 and the gas supply pipe 13 may be provided inside the support rod 1.

Further, a blower other than the exhaust mechanism of the vacuum cleaner 15 may be used as the dryer 14.

[0018]

According to the present invention, since the above configuration is adopted, the cleaning solution is ejected into the sensing portion by supporting the support rod, surrounding the sensing portion of the smoke sensor with a pot-shaped member, operating the suction device and the pump. In addition, by sucking the dust, the sensor can be easily cleaned without disassembling the smoke detector and without having to climb a stepladder or the like.

Further, since the smoke detector is operated by the cleaning liquid diffused in the sensing section, the operation of the smoke detector can be checked simultaneously with the cleaning.

In addition, after cleaning, the sensing portion can be quickly dried by hot air sent from a dryer.
